The objective of this pilot study was to evaluate the attitudes and self-efficacy of advanced pharmacy practice experience (APPE) conference leaders after completing the Well-being Promotion (WelPro) training program developed at the University of California, San Francisco (UCSF) School of Pharmacy. The WelPro training program was developed to equip participants with the knowledge and tools to assist APPE students in distress and promote student wellness. After completing the WelPro training program, a 20-item survey was administered to 10 conference leaders via a web-based survey tool to assess their attitudes about burnout and self-efficacy in assisting students in distress.

Herein, we have prepared a novel electrochemical aptasensor for rapid and sensitive detection of serotonin by using the pre-designed and prepared DNA aptamers. In the absence of serotonin, the electron transfer rate on the aptasensor was faster than that in the presence of serotonin due to the hairpin structure of the aptamer was loose and MB could be closer to the electrode surface.

Multivariate statistical analysis, geostatistics, and global information system (GIS) techniques are used to study:the spatial distribution characteristics of soil As, the effects of various agricultural products on As enrichment, and to compare the characteristics of the As content of agricultural products and root soils in spatially significantly and non-significantly autocorrelated regions. The As content of soil samples were relatively low, and the average As contents determined for agricultural land and non-agricultural land were 9.

A total of 1765 soil samples were collected from the Cele-Ruoqiang area. The contents of soil As, Cd, Cr, Cu, Hg, Ni, Pb and Zn were analyzed using the pollution load index method.

The MIP/GO/GC electrode exhibits an excellent ability of specific binding of EGCG and a rapid electrochemical response, high sensitivity and selectivity for determination of EGCG. This prepared MIP sensor presents distinct advantages over conventional electrochemical methods for EGCG determination because it is a one-step preparation and the template molecule can be easily removed by cyclic voltammetry scans, and no elution reagent is required.

Hemoglobin (Hb) has been successfully immobilized on the 3DOM GTD film and the fabrication process was characterized by Raman and UV-vis spectra. The results indicated that the Hb immobilized on the film retained its biological activity and the secondary structure of Hb was not destroyed.

The three-dimensionally ordered macroporous gold-nanoparticle-doped titanium dioxide (3DOM GTD) film was modified on the indium-tin oxide (ITO) electrode surface and used for the hydrogen peroxide biosensor. The direct electron transfer and electrocatalysis of horseradish peroxidase (HRP) immobilized on this film have been investigated.

The interaction mechanism of thionine (TH) and calf thymus DNA (CT-DNA) was studied with UV-Vis absorption spectoscopy, fluorescence spectroscopy, circular dichroism (CD), and X-ray photoelectron spectroscopy (XPS). It was demonstrated that in the pH 7.2 phosphate buffer solution, the interaction of TH and CT-DNA is in the intercalative mode.

Oxygen of two propionic acid groups of the heme group in an MP-8 molecule, leading to an increase in the non-planarity of the porphyrin ring of the heme group. The increasing extent in the non-planarity of the porphyrin ring of the heme group due to the interaction of La3+ and MP-8 molecule would be significantly decreased because NaCl could increase the aggregation extent of MP-8 molecules. Although methanol can reduce the aggregation extent of MP-8 molecules, it has little influence on the increasing extent in the non-planarity of the porphyrin ring of the heme group due to the interaction of La3+ and MP-8 molecule.
